Section 1 Introduction

1.1 Overview The new Isco 3780 Sampler is designed for hazardous locationinstallation and carries the IEC (International ElectrotechnicalCommission) rating for Zone 1 (compliant with UL Class I,Division 1 requirements) operation. It provides users with aviable alternative to manual sample collection in hazardous loca-tions. It has also been given approval for Zone 1 installation byTUV, an internationally recognized testing lab.

The IEC Zone 1 classification refers to areas where ignitable con-centrations of explosive gases are likely to exist periodicallyunder normal operating conditions. IEC standards are acceptedin the US, and operate in parallel with the UL/CSA Divisionratings system.

The 3780’s Zone 1 rating is achieved using specialized batteriesand a cast aluminum case that contains the controller compo-nents. In addition, a unique programming interface eliminatesthe need for complex keypad entry of program parameters, andserves to maintain the operational safety required for Zone 1applications.

Section 2 Installation

2.1 Overview Section 2 explains principal setup and sampler operation,including physical placement and connections for power andexternal input, basic function and sample collection.

2.2 Placement of the Sampler

To avoid the formation of air slugs and to ensure that the correctquantities are sampled, place the sampler above the samplesource on solid, level ground so that the suction line slopesdownward to the source. The standard suction line is equippedwith a weighted strainer at its opening which prevents large par-ticles from entering the tube, and the tube from rising to thesurface. For cold weather operation, additional tube insulationmay be necessary.

2.3 Battery Operation During battery operation, the sampler is run by an externalbattery. It is essential to charge the battery prior to starting thesampler. An external battery charger (not Zone 1 rated) can beused.

The battery charger may under no circumstances be used in riskareas. The charging time depends upon the remaining charge ofthe battery. A fully discharged battery must be charged for atleast 24 to 48 hours.

For trickle charging, the battery should be connected continu-ously to the battery charger since the charging process is regu-lated automatically. The battery is protected by means of aswitch, which prevents deep discharge. If the voltage becomes toolow, the sampler switches off automatically.

WARNINGWARNINGThe battery must be recharged after using battery operation mode.

The battery must NOT be charged using the battery charger inplaces with high explosion risk, since the battery charger itself isnot ex-protected.

When the sampler is powered by an external battery, it can beused immediately after the battery has been exchanged. Theused battery can then be recharged.

2.4 Connecting the Ex-protected Connector

Sampler models designed for operation with an external batteryor the ex-protected AC-charger are suitably equipped with anex-protected connector.

To connect it properly, rotate it a quarter-turn clockwise whileexerting slight pressure. The connector should click into position.

Isco 3780 Zone 1-rated SamplerSection 2 Installation

2.5 Sampler Connections

WARNINGWARNINGIn risk areas, only self-protected circuits may be used!

WARNINGWARNINGTo ensure safe operation in hazardous location areas, all wiring must be performed by a qualified electrician in accordance with governing directives.

NoteIn the connector box, the brown wire is "+" and blue "–".

WARNINGWARNINGAny flow meter or external device to be operated with the sampler in an ex-area must be self-protected.

WARNINGWARNINGIf the sampler is to be operated in manholes or in the open, the protective cover must be placed over the control housing for splash protection. Only when the protective cover is in place will the sampler have the protection degree IP 65.

2.6 Basic Function and Design

The sampler allows sequential or composite samples to be takenof waste water from lakes, rivers, and other waters at timedintervals, with the option of flow-poportional sample volumes.The sampler is equipped with a peristaltic pump. Each sample iscollected according to the following sequence:

1. Suction Line Purge

2. Water drawn until detected at sampling head

3. Delivery of preset sample volume

4. Suction Line purgeThe sample time is stored by the control module.

In subsequent collections, if the sampling head does not identifywater after 1.25 times the duration of the first sample collection,the suction line will be purged, error 5 will be displayed, and anew sample process will be initiated for the next sample col-lection.

The samples are deposited either into one single vessel (com-posite sampling), or into 12 bottles by means of a distributor arm(sequential sampling).

For sequential sampling: Before switching the sampler on, man-ually set the distributor arm to bottle 12. The reason for this isthat when the sampler is switched off, the controller alwaysadvances to the next field; i.e., the next bottle in sequence will beset as bottle #1.

3.2 Operation The sampler is operated by means of a 24-position rotary selectorswitch and one confirmation button.

NoteThis manual often refers to pressing “keys.” In reality, thistranslates to selecting the indicated number or function withthe rotary selector switch and then pressing the ENTER but-ton.

Example:

3.3 Switching On the Sampler

To switch on the sampler, the (ON) key must be pressed. Theversion of the control unit should be indicated briefly.

3.4 Viewing Errors If the sampler displays [ERRORS!], some errors from the lastprogram sequence are still stored in the error file. To see theseerrors, press (F). Errors are displayed in reverse chronologicalorder, i.e. the last error which occurred is displayed first. Theerror number, date, and time of start and end of error are dis-played, in that order. After this, the display reads [CONTIN.?].By pressing (F), the next error can be seen. If there are nofurther errors in the file, the message [F END!] appears. Thedisplay of the contents of the error file can only be stopped bypressing (F) repeatedly until the message [CONTIN.?] is dis-played and (C) is pressed. A program cannot be restarted untilthe errors are cleared. To clear the errors, press (C) again, and

when the message [CLEAR ?] appears, press [ENTER]. To savethe errors, let the message time out. The message [ERRORS!]then appears again.

3.5 Starting a Program When sampler is started, it displays the last program used. Forexample, [P0start?]. This program can be started directly bypressing (START).

If the displayed program number is pressed, the sampler dis-plays the start and stop time with date and time of day of the lastprogram sequence. To start another program, select the requiredprogram by pressing the corresponding program number andpressing the (START) key.

3.6 Starting a Program with Start Delay

To start a program at a certain time, or after a certain period oftime has elapsed, a delay in relative or real time can be enteredby pressing the (GREEN_CLOCK) key. When this key is pressedrepeatedly, the display is switched between these two delays.Thus, when the (C) key is pressed, the delay input function canbe exited without having to enter any data.

When the display reads [DT REL.?] a relative delay can beentered. The desired delay can now be entered in hours (hrs) andminutes (min), the longest possible time being 199hrs and59min.

When the display reads [DT REAL?] a real delay, that is, dateand time of day, can be entered. To enter a real time, press

3.11 Pausing a Program For maintenance and monitoring, the (STAND BY) key must bepressed in order to stop the pump and the distributor arm. Thedisplay then shows the message [STDBY!!].

A sample which is currently being taken, or a step being carriedout by the distributor arm, will not be interrupted. In this case,the display will show first the message [WAIT!!] and then[STDBY!!].

To exit standby mode, press either (START) or (ENTER). When(START) is pressed, steps not yet carried out by the distributorarm due to the program pause will be performed. Sampling,however, will not. When (ENTER) is pressed, missed sampleswill also be collected.

3.12 Halting a Program in Progress

To stop a program prematurely, press the (STOP) key. Thedisplay then reads [REALLY?]. To “really” stop a program, press(ENTER). To reject the program stop, press the (C) key.

3.13 Editing User Programs To edit user programs, stop the current program, press the (P)key; [code??] will be displayed. Enter the code number 4955. Thedisplay then reads, for example, [P5 edit?], the program numberalways being that of the last program executed; in this case,program number 5. To edit the suggested program, press(ENTER). To edit another program, select the program you wishto change by pressing the corresponding number key (0-9) and(ENTER).

To quit the editing mode, press the (C) key. The display nowreads again [code??].

If you have selected a program number and confirmed this with(ENTER), the sampler now begins to display several programparameters, which are different for each sampler model.

1. Select the type of program. You can choose between two program types:[T1 ?] Time Mode

[F mA ?] Flow Mode with 0-20 mA or 4-20 mA

[V IMP?] THIS PROGRAM NOT SUPPORTED

[E1 ?] THIS PROGRAM NOT SUPPORTED

[E2 ?] THIS PROGRAM NOT SUPPORTED

Using the (C) key allows you to switch between differenttypes of programs. When the type of program you wish toedit appears in the display, press (ENTER).

Depending upon the type of program selected, the displaywill show the program-specific parameters used so far. Toretain these parameters, press (ENTER). To edit them,press the number keys (0-9), the (C) key and (ENTER).

2. Selecting Bottle Volume. The following bottle volumes can be chosen:[BV 0.5L?] Bottle Volume 500 ml

[BV 10L?] Bottle Volume 10 liters (2.6 gal)


3-7

To switch between bottle volumes, press the (C) key. Whenthe desired bottle volume appears, press (ENTER).

NoteThe additional volumes displayed are not currently supportedby Isco.

3. Entering the Number of Bottles. An amount of 1 or 12 bot-tles can be selected.[BN 12]

To enter the number of bottles, use the number keys [1,2]and (ENTER). To correct wrong entries, press the (C) key.

4. Entering the Sample Interval. The sample interval can range from 0.1 minute to 999 hrs and 59.9 minutes.[SI 5m]

To enter the sample interval, use the number key [0-9] and(ENTER). To correct wrong entries, press the (C) key.

[SI 5.0m]

Use the number keys (0-9) to enter the sample interval inminutes and press (ENTER).

[SI 0h]

Use the number keys (0-9) to enter the sample interval inhours and minutes. Press (ENTER) to confirm each.

5. Entering the Sampling Duration (program length). The sampling duration can be programmed in hours and min-utes and can range from 1 minute to 999 hours and 59 min-utes.Use the number keys (0-9) to enter the sampling durationin hours and (ENTER).

[SD 0m]

Use the number keys (0-9) to enter the sampling durationin minutes and press (ENTER). To correct wrong entries,press the (C) key.

6. Sample Volume. The sample volume is calculated from the entered values. Normally, the sample volume displayed should be accepted by pressing (ENTER).

— Sample volumes of less than 100 ml will be displayed to one decimal place.

— Sample volumes between 100 ml and 2500 ml will be displayed as ml.

— Sample volumes greater than 2500 ml will be displayed as l.

The sample volume can be manually decreased orincreased by up to 50% (for example, in the case ofextended suction height, where the calculated volume mayfall short). To do this, use the number keys (0-9) to over-write the displayed value, and press (ENTER) or the (C)key to correct your entry.


3-8

If you have changed the sample volume, the display showsthe actual amount over or under the calculated sample vol-ume as a percentage. If, for example, the sample volume[SV 20.8 ml] is reduced to 15.5 ml, the display will read[SV -25%].

For sample volumes below 2ml, the display reads [DQ <2ml]. This is indicates possible inaccuracy due to the sam-ple volumes being so small. In all cases, the processor willsuggest a sample volume between 5ml and 2500 ml.

7. Activating and Deactivating the Suction Purge. The suc-tion purge function can be activated or deactivated after each collection in order to take samples in pressurized lines.[PU ON ?] Suction line will be purged.

[PU OFF ?] Suction line will not be purged.

The (C) key toggles between these two options. To selectthe desired option, press (ENTER).

8. Entering the Measuring Range (Only possible for program F mA)[0-20 mA]

Initially, the display blinks, signaling that the bottomvalue of the measuring range is to be entered. Either 0mAor 4mA can be selected.

Use the number keys (0, 4) to enter the desired value andpress (ENTER).

Signal currents at or below the bottom value will result in0ml sample volumes. After the bottom value has beenentered, the display blinks again, signaling that the topvalue is to be entered. Use the number keys (0-9) to enterthe desired value to one decimal place, and press (ENTER).Signal currents at or above the top value will result insample volumes of 100%.

9. Switch-over Value (only required in the case of program F mA). The sampler is able to switch over to time mode when there is a permanently low flow of signal current. If the sig-nal current is at or below the switch-over value, the maxi-mum possible sample volume will be taken. If the signal current rises above the switch-over value, the sampler will switch again to the flow mode of operation.If the sampler is to operate without a switch-over value,enter 0.0mA. Each time the signal current falls below theswitch-over value will be stored in the error file.

[SO 0.0mA]

To enter the switch-over value, use the number keys (0-9).It can be entered in 0.1 mA increments within a range of 0to 10mA. After entering a value, press (ENTER). To correctwrong entries, press the (C) key.

10. Switch-off Value (will only be viewed in the case of pro-gram F mA). If the signal current is at or below the


3-9

switch-off value, the sampler will not take any samples. If the signal current exceeds the switch-off value, the sam-pler will again automatically take flow proportional sam-ples.If the sampler is to operate without a switch-off value,enter 0.0mA. Each time that the signal current falls belowthe switch-off value will be stored in the error file.

[SX 0.0mA]

To enter the switch-off value, use the number keys (0-9). Itcan be entered in 0.1mA increments within a range of 0to10mA. The switch-off value must be 0.5mA lower thanthe switch-over value. After entering the desired value,press (ENTER). To correct wrong entries, press the (C) key.

3.14 Restoring Factory Default Settings

If original programs have been deleted or overwritten, they canbe returned to factory settings using the preset function.

It may be necessary to first terminate a running program. First,press the (P) key.

The display then reads [code ??]. By entering the four-digit codenumber 0990, the preset function will be started.

The display now reads [PRESET?]. To start the preset function,press (ENTER). To exit it, press the (C) key.

If (ENTER) is now pressed, the display will ask for the number ofthe program to be reset [PRES.0?]. Use the number keys to enterthe desired program number and press (ENTER). The displaynow asks for the bottle volume and the number of bottles withwhich the program is to be reset.

[BV 0.5L?]

To step through bottle volumes, press the (C) key. When thecorrect bottle volume appears, press (ENTER).

[BN 12]

To select the desired number of bottles, use the number keys (1,2)and press (ENTER). To correct wrong entries, press the (C) key.

After the number of bottles has been confirmed, the program willbe reset and the display will read

[PRES.0!].

After this, the message [CONTINUE?] appears. To reset anotherprogram, press (ENTER) or a number key (0-9). To exit thepreset function, press the (C) key.

CAUTIONResetting a program means that the selected user program willbe overwritten with the original parameters indicated in Table3-3.


3-10

The sample volume will be calculated from the bottle volume andnumber of bottles entered prior to the resetting of the program.

3.15 Language To select another language for the display, it may first be nec-essary to terminate a running program. Next, press the (P) key.The display will then read [code??]. Activate the languagefunction by entering code number 4918. One of four languagescan now be chosen by using the (C) key, and confirmed with(ENTER).

Section 4 Maintenance

4.1 Overview The following section contains routine maintenance instructionsfor the 3780 sampler, including regular cleaning steps, tubingreplacement, battery maintenance, and recommended inspectionintervals.

4.2 Maintenance

WARNINGWARNINGThe controller housing may only be opened by the manufacturer or persons authorized by the manufacturer. Improper opening or closing of the housing results in loss of ex-protection.

WARNINGWARNINGAlways disconnect power to the sampler before opening.

To ensure proper function, the sampler should be cleaned regu-larly, depending upon the degree and nature of pollution of theliquid:

1. Clean the fluid sensor using the enclosed brush.If the water is highly polluted or oily, the fluid sensor mayrequire daily cleaning.

2. Remove and clean distributor.

3. Rinse cycle:

a. Switch on the sampler.

b. Immerse suction line in a detergent.

c. Press the (.) key to start the rinse cycle.

d. Repeat rinse cycle several times.The silicone tube in the pump head is subject to natural wear dueto the pumping process. Furthermore, the tube life will depend agreat deal on the composition of the sample liquid.

Replace pump tube with silicone tubing of .3 in. inside diameter,.5 in. outside diameter, and of 11 in. length. Other tube dimen-sions may result in lower transport velocities or damage to thepump.
